Thing is, guys whose primarily skillset involves being large, dunking the ball, and grabbing rebounds, and who have at best theoretical range and ability to defend pick and rolls / switch on perimeter players ... just have a limited ceiling in today's game.
I mean, Rudy Gobert is absolutely great at pretty much all of that stuff, and he's a borderline All-Star.
The fact is in today's league to be really valuable with Ayton's skillset you have to be incredible.
To be really valuable with Tatum's skillset you pretty much just have to be what Tatum is already, just a bit more assertive and consistent.
The thing is... Ayton is only 20 years old. He's still 6-9 years away from his prime. When you talk about being valuable in "today's league"... we don't know that the trends of today's NBA will still be the trends of the NBA 6-9 years from now. Maybe coaches figure out how to run super efficient offenses through the low post and that becomes the trend? You never know.
9 years?!
A typical NBA player's prime is between ages 26-29. So yeah he's 6-9 years away from his prime. Typically its a slow decline in ages 30, 31, 32 and then the drop off starts to become steeper. Again, this is just the average player... it doesn't describe everyone.
Big333 gave some context already with Hakeem, Robinson and Ewing, but some more context if needed is MJ and Lebron both won their first rings at age 27. Shaq's 3 consecutive rings came at 27, 28, and 29.
For fun, I'm going to look up the average age of the league MVP since the turn of the century.
